never too late. Cryptocurrencies are our future, and so it's nice to understand processes. To invest in BTC maybe not fresh idea, and better to search new interesting project, like ETH on the start will bring more profit. Even though cryptoworld is interesting and perspective if shut eyes on scammers 
In my opinion, it is better to be late than never. There is always a right time for each and everything and the ones who havent invested their money earlier in this world of bitcoin, now is the chance to get into this world by investing some good amount of money as the market value is little low now-a-days. You just need to remain positive and that you need to keep on increasing the knowledge for making better decisions.
